I guess it depends what you mean by "integration".

I successfully run a HylaFAX server with a Patton 2977 connected through a 
Digium TE405P.

Well, for one thing, t38modem comes from OpenH323, not Asterisk, and it 
cannot be used with Asterisk as Asterisk does not yet support T.38.

As for using spandsp's txfax/rxfax to replace HylaFAX's 
faxgetty/faxsend... it should be possible to write a "wrapper" script and 
then set HylaFAX's "SendFaxCmd" to point to your wrapper script instead of 
the faxsend binary.  The wrapper script would need to trigger txfax 
via a .call file in the Asterisk spool directory.  There will be some 
complications with regards to return status and requeuing of jobs (which 
is why I've not attempted this myself).

As for replacing faxgetty... that should be fairly straight-forward by 
simply making rxfax dump the received faxes into the HylaFAX recvq 
directory.
